When server resets there are almost always 8 h lions in zone. the drop rate accord to magelo is 1.4%. There are no know place holders for them, Genocide seems the best way to farm. if you clear the entire zone 10 times you should get 1 pelt.

Not to sound harsh, but your wording is off. Genocide is when you wipe out your own race, homicide is random killing with purpose. So, unless your a Lion or maybe a vah shir might be considered, you can't commit genocide on the lions.
